Problems solved by technology

[0002] Heart failure is a common and potentially fatal disease in humans. Although the hospital tries its best to treat it, it is often difficult to control and cure it clinically.
In particular, "heart failure with preserved ejection fraction (HFpEF)" has seen a marked increase in prevalence over the years, but its treatment remains a challenge for clinicians

Abstract

The invention relates to the technical field of medical equipment, in particular to a hole cutting type non-implanted atrial shunt device. The device comprises an outer tube and an inner tube arrangedin the outer tube, wherein the end part of one of the outer tube and the inner tube is connected with an ablation assembly; the other end of the other of the outer tube and the inner tube is connected with an anastomosis assembly; the ablation assembly is connected with a radio frequency ablation instrument; and when the inner tube and / or the outer tube are / is moved, and the ablation assembly andthe anastomosis assembly move oppositely to cut an atrial septum located between the ablation assembly and the anastomosis assembly. A hole is formed in a radio frequency mode by using the ablation assembly and the anastomosis assembly, and the formed hole is not prone to being closed again and allows left atrial blood pressure to be effectively guided to the right atrium, so the purpose of treatment is achieved.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a hole-cutting non-implantation atrial shunt device. Background technique [0002] Heart failure is a common and potentially fatal disease in humans. Although hospitals try their best to treat it, it is often difficult to control and cure it clinically. In particular, "heart failure with preserved ejection fraction (HFpEF)" has seen a marked increase in prevalence over the past few years, but its treatment remains a challenge for clinicians. [0003] Heart failure with preserved ejection fraction is a concept of heart failure proposed relative to systolic insufficiency, mainly referring to heart failure that occurs when left ventricular diastolic function is reduced and systolic function is relatively normal. The disease is characterized by left ventricular stiffness with reduced compliance and impaired relaxation, resulting in elevated end-diastolic pressure. About o...
